2. Section 1 Living Things Organism Any living thing Made of cells Cell
The smallest unit of a living thing that carries on the functions of life

3. 6 Characteristics of Living Things
Made of cells
Grow and Develop
Respond to Stimuli
Maintain Homeostasis
Use Energy
Reproduce

4. 3 Need of Living Things A suitable place to live Water Food

9. Section 3: Cell Structure
Anton van Leeuwenhoeck
Dutch fabric merchant who perfected the microscope.
Robert Hooke
Cut a thin slice of cork and viewed it under a microscope.
Viewed empty little monk “cells”
Matt Schleiden and Theordor Schwann
Observed plant and animal cells and concluded that all living things are made of cells.
Rudolf Virchow
Proposed that all cells come from pre-existing cells.

10. Cell Theory was formed All organisms are made of one or more cells.
The cell is the basic unit of organization in organisms
All cells come from other cells

11. CELL PARTS

12. Animal Cells Cell Memrane
Protective layer that surrounds the cell and regulates movement into and out of the cell
Cytoplasm
Gelatin-like substance that fills the cells and carries on life processes
Ribosomes
Structure that manufacture proteins
Nucleus
Contains DNA and controls the cells functions
Mitochondria
Energy releasing agents, break down food and water
Endoplasmic Reticulum
Series of folded membranes that move materials throughout the cell
Golgi Bodies
Package and ship materials within the cell and outside of the cell

14. Plant Cells 3 differences from animal cells Cell Wall Chloroplasts
Stiff outer covering that gives the cell rigidness, shape, and protection
Chloroplasts
Green organelles that capture sunlight and use it for photosynthesis.
Contain chlorophyll
Vacuole
Water and mineral storing area that needs to be full for the plant to be rigid.

16. Cellular Organization
Cells
Smallest unit life can be broken down to
Tissues
A group of similar cells performing a certain function
Organs
A group of tissues performing a function
Organ system
A group of organs performing a life sustaining function
Organism
A collection of organ systems creating a living creature
